Performance Evaluation and Response of Yield Components and Yield of Bread Wheat to NPK Fertilizers at Hidebu Abote District of North Shewa Zone, Oromia

Abstract

A field experiment was carried out on nitisols of Hidebu Abote district, North Shewa Zone, Oromia where wheat production is severely constrained by lack of an appropriate rate and types of fertilizer recommendation to evaluate wheat crop response to NPK fertilizer application. Fifteen NPK nutrients levels were considered and applied as treatments along with control (no fertilizer) at yaya Deka Bora peasant association were arranged in randomized complete block design (RCBD) with three replications at two farmers field. The ANOVA result indicated that plant height (PH), above ground biomass yield (AGBMY), straw yield (SY), Thousand grain weight (TGW), grain yield (GY) and harvest index (HI) of bread wheat showed significant (P ≤ 0.05) response to the NPK fertilizer application at both sites. The highest AGBMY (13.61 and 12.46 tons ha-1), SY (8.13 and 7.33 tons ha-1) and GY (5475.00 and 5414.33 kg ha-1) were recorded with the application of 69:30:20 NPK fertilizer combination at (site 1 and site 2) respectively and the lowest were recorded on control treatments. However the highest PH (103.8 and 97.27 cm) at site 1 and site 2 was recorded respectively with the application of 92:10:20 NPK nutrients combinations. Both the statically and economical analysis showed that 69:30:20 NPK kg ha-1 of fertilizer application results in higher yield and economically profitable for bread wheat production in the study area. However further research experiment with multi locations, cropping seasons and different bread wheat cultivar have to be required in order to give best conclusive recommendation for the farmers.

The levels of essential nutrients and nonessential metals in different varieties of teff produced in Hidabu Abote Woreda, Oromia, Ethiopia

“…Although there was no industrialization in the study area, continuous agrochemical chemical application was identified in Hidabu Abote Woreda, which may contribute to the accumulation of metals in the soil (Abebe et al., 2020 ; Feyisa et al., 2022 ). The pH of the soil in Hidabu Abote Woreda has been shown to be somewhat acidic, which may affect the availability of nutrients and plant uptake.…”
